A decentralized app (DApp) is software that runs on a decentralized network. We are familiar with standard apps controlled by providers such as Google, Amazon, and eBay. Dapps are different because no such control exists. Users deal directly with each other, and the blockchain records it. This serves as proof that the transaction took place.
Dapps are best suited to trading, gambling, gaming, and other situations that require transactions to be recorded. Because of its blockchain foundation, a dapp cannot ever break down or go offline. If one or more nodes become unavailable, the dapp continues to work because all the other nodes remain functional.
